The upgrade costs to get any 'sniper' gun to be able to out distance an AEG accurately are quite high. The stock spring on almost all bolt action snipers isn't really that different from those on AEGs. Also for games themselves, most experienced players will not play with snipers or individuals using high powered rifles who do not have much expierence.
In terms of CQB, nothing beats a GBB pistol. For mid-long range games AEGs (and now fullsize GBB rilfes) are king. The sniper role isn't really for everyone, and IMO pistols are the most fun out of all the above.
Get AV'd, start reading, and get out for some games.
